igraph R |如何为每个节点添加第二个内圆？,r,plot,nodes,igraph,R,Plot,Nodes,Igraph,我想在当前顶点上添加第二个内圆。它应该与某个变量成比例 这里有一个例子： 我已经知道如何处理主圆，也就是顶点大小 variable1 <- c(20,40,60) # this will define the size of the vertices g1 <- graph(edges=c(1,2, 2,3, 3,1), n=3, directed=F) V(g1)$size <- variable1 # this assigns the vertices size to t

我想在当前顶点上添加第二个内圆。它应该与某个变量成比例

这里有一个例子：

我已经知道如何处理主圆，也就是顶点大小

variable1 <- c(20,40,60) # this will define the size of the vertices
g1 <- graph(edges=c(1,2, 2,3, 3,1), n=3, directed=F)
V(g1)$size <- variable1 # this assigns the vertices size to the igraph object 'g1'
plot(g1)
variable2 <- c(10,20,30) # this would be needed for a second, internal circle, ideally in a different color

variable1您可以尝试


library(igraph)
variable1 <- c(20,40,60) # this will define the size of the vertices
variable2 <- c(10,20,30) # this would be needed for a second, internal circle, ideally in a different color
g1 <- graph(edges=c(1,2, 2,3, 3,1), n=3, directed=F)
V(g1)$size <- variable1 # this assigns the vertices size to the igraph object 'g1'
coords <- layout.auto(g1)
plot(g1, layout=coords, vertex.frame.color="orange", vertex.color=NA, vertex.label = NA)
plot(g1, layout=coords, vertex.size=variable2, add=T, vertex.color="lightgray")



库（igraph）

变量1很好的技巧。是否可以使边缘从外环开始？@fibar是的，只需将
edge.lty=“blank”
添加到第二个边缘即可。就目前而言，它过度绘制了第二组边。
